摘要
通过快速检测条件的优化,确定了单针进样一次分析岩屑顶空气二氧化碳、氧、氮的气相色谱最佳分析条件。运用准确度和精密度对方法进行评价,结果证明该方法精密度高、准确度高。本方法具有设定色谱条件简单,分析速度快,所需气量小的特点。通过在已知区的应用,取得较好的应用效果,适合于油气化探地表勘探的样品以及模拟气、天然气中二氧化碳、氧、氮的测定。
By optimizing the detecting conditions,the authors obtained the best condition for analyzing carbon dioxide,oxygen and nitrogen in debris top gas by GC in a single run. Accuracy and precision were used to evaluate the method. It is shown that this method has high accuracy and precision. This method is characterized by simple chromatographic conditions,fast analysis speed and small gas volume and it has been proved to be effective in known areas. It can be used to analyze carbon dioxide,oxygen and nitrogen in geochemical subsurface exploration samples,simulated samples and natural gas samples.
